"Slavery Mark?"
Si Xing glanced at the Legendary Level 1 standing before him.
A Servant Mark only puts one under the control of another in life and death, but if life seems unbearable, death in the form of suicide could be a way of escape.
But a Slavery Mark...
Not only does it require the subject to fully recognize and accept the power of the mark, but it also gradually changes the subject's way of thinking, making them completely devoted to the enforcer's will, even to the point of losing their individuality.
To many legends, this was certainly worse than death.
However...
From the looks of Yu Shengjin, Si Xing somewhat understood that the man before him must be carrying a grudge of deep hatred.
There were numerous legends in the vast starry skies who shared a similar fate.
There were countless others who were willing to sacrifice themselves for vengeance.
